SCALE AND, RULE HOLDER.

SPECIFICATION forming part of Letters Patent No. 332,958, dated December2 1885- Application filed September 9, 1885. Serial No. 176,564. (Nomodel.)

To all whom it may concern;

Be it known that I, CHARLES A. SMITH, of Pawtucket, in the county ofProvidence and State of Rhode Island, have invented certain new anduseful Improvements in Scale and Rule Holders, of which the followingisa full, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification.

This invention pertains to an improved holder designed to hold or clamparule, scale, and such like articles,which in themselves are necessarilyawkward to manipulate, and to so adjust them as to gain the best lighton the scaled surface and to afiord convenient handling of the same.

The nature of the device is a strip of sheet metal or other suitablematerial flexed upon itself longitudinally to make of it a springclampfor its entire length, and to allow one flange to come over on the faceor front of the object held, and the other flange to project rearwardand form a rest or rigid supportfor said object, as hereinafter fullyset forth.

Figure 1 represents a perspective view of my improved holder clamping aportion of a scale adjusted for use. Fig. 2 represents a cross-sectionview of the same. Fig. 3 represents a cross-section view of the holderand scale, and shows a modified form of the former.

In the drawings, A designates the entire holder, made of sheet metalbent upon itself longitudinally, forwardly convexly, and rear- Wardlyconcavely to form a springclamp between the front or clamp flange, a andthe bend or fold a, the spring force of which is derived from the loopor rounded portion a 'a designates the back or support flange, forming asupport or rest for the device when adjusted with a scale or rule, B,for use.

I make various modifications in the bends or flexures of my device forthe purpose of affording a stronger spring to-the clamp, or in order tovary the angle of the face of the scale as it may be desired.

I desire to make no specified claim as to material or form, but broadlyclaim as a new and useful device in a holder for scales, rules, and thelike- 1. A strip longitudinally flexed forwardly convexly, rearwardlyconcavely, forming, respeetively, a clamp-flange adapted to clamp andrest on the rule, and a support-flange adapted to adjust the face-angleof said rule, as specified.

2. The strip A, flexed, as described, to form a clamp-flange, a a loop,a a bend, a, and a supportflange, a, for the purpose described.

CHARLES A. SMITH.
